It started last season when Altuve was caught in the Astros locker room crooning the Backstreet Boys’ 1999 hit, “I Want it That Way,” which went viral.

The group saw the video, and liked it so much that they’ve jumped on the Astros bandwagon, sharing a video of support to Altuve and the team.

“There was an Internet sensation video that happened with José Altuve from the Astros, the second baseman,” BSB singer Brian Littrell said in the Instagram video posted before World Series Game 6. “The dude is 5-foot-6, and he’s going to be the AL MVP, I think so. We want to tell you congratulations, good luck in the World Series, go Astros, God bless you!”
